Abstract

The temperature- and concentration-dependent aggregation of EO 78PO 30EO 78 triblock copolymer in aqueous solutions has been studied in the concentration range from 5 to 200 g/dm 3 at 25°C, 45°C and 60°C. The influence of o-xylene on the micellization was measured at various (from 5 to 40) molar ratio of additive to polymer. The aggregates were described as polydisperse spheres with tethered Gaussian polymer chains. The results of the least-squares fit is briefly discussed.
